IMPROVEMENT IN TRANSMITTING TIME-MOVEMENTS TO DISTANT DIALS.

Specification forming part of Letters Patent No. 140,661, dated July 8,1873 application filed March 21, 1873.

To all whom it may concern:

Be it known that I, HERMANN J ULIUS WEN- ZEL, of San Francisco, in theState of Galifornia,have invented an Improvement in Oonnecting DifferentDials with a Time-Piece, of which the following is a specification:

This invention is intended to actuate two or more dials synchronouslyfrom one timepiece, and that without any material loss by friction andwithout much resistance to the movement of the time-piece.

A bellows or pump has been operated periodically by clock-work to forceair or liquid through a tube to operate a distant mechanism for movingthe hands upon a dial or dials in unison with the main'clock-movements,but the changes of temperature and atmospheric pressure were liable toderange the operation.

My invention consists in cylinders that are raised and lowered byclock-work, and the open lower ends enter liquid contained in a vesseland force the confined atmosphere to the distant mechanism where theatmosphere acts upon liquid to change its level in a vessel, and therebymove a fioat and the mechanism that operates the dials. Theactuatingcylinder rises entirely above the liquid each movement, so thatthe pressure of the atmosphere within the tubes of the apparatus isequalized and no derangement can result from thermometric or barometricchanges. The resistance offered to the time-piece by the cylinders thatare forced down in the liquid is partially compensated by aliquidequalizer between the time-piece and the cylinders.

In the drawing, Figure 1 is an elevation representing the apparatus atthe time-piece, and Fig. 2 represents one of the dials and the means formoving the hands. Figs. 3 and 4 illustrate modifications in theratcl1et-andpawl mechanisms.

The shaft or is part of, or connected with, any suitable time-piece, andrevolved once in a minute or in any regular interval of time. Upon thisshaft to is a cam, 12, that gives motion to the oscillating lever 0,through the medium of the arms and rollers (1. Near the ends of thelever c are cylinders e e, suspended by wires or rods from the joints hh, and

these cylinders are open at bottom ends, closed at top, and hang withinthe cups or vessels f f, containing liquid such as glycerine, and in thecenter of these vessels ff are tubes g, rising above the surface of theliquid and open at the upper ends. As the lever c is oscillated thecylinders c c are raised and lowered in the liquid contained in thevessels f f, and, in so doing, the air is alternately drawn in andforced out through the tubes 9 and through India-rubber or other tubesh, that extend to the apparatus hereafter described at the dials in thevarious places where it is necessary to indicate the time, or performany other operation. The cylinders c 6 should lift out of the liquideach upward movement, so that the atmosphere within the tube and thatoutside the same equalize in pressure, and no difficulty arises fromchange of atmospheric condition, such as would result if the air wasconfined. As the cylinders c e are alternately forced down into theliquid the resistance becomes greater, both in consequence of theimmersion of the cylinder and the slight compression of the air, and, atthe same time, theother cylinder is being lifted and the air drawn intothe same; hence there is a force at both ends acting against theclock-work. I therefore provide for neutralizing this by an equallzerapplied to the lever 0, consisting of two vessels, k 70, one at each endof the lever and connected by a tube and containing glycerine, mercury,or other liquid, the size or shape of the vessel being proportioned tothe weight required. When the lever 0 stands level the forces are allbalanced, but as it is tipped the liquid runs into the lowest vessel andbecomes a sufficient surplus weight to counterpoise the other forcesaforesaid. At the cloclrdial the proper hands 8 and connecting gearingare provided, and also a ratchet-wheel or wheels, and a pawl or pawls,to turn the wheels through the agency of a lever, l, and fioat, m, thatis raised or lowered by the alternate action of the atmosphere in thetubes g and h. The float m is within the compartment 1", and near it isa second compartment, 8, that communicates with r by the opening 4:, andthe tube h is connected to a pipe at the closed end of compartment 8. Itwill 2 IMWAEGH now be apparent that when the cylinder 0 is i'oreed downinto the liquid, in f, the water or other liquid will be forced by theatmosphere out of the compartments, and, rising in r, will float theball on and operate the clock-movement to the hands; thus the float onwill move up and down with the cylinder 0.

I have shown the levers 2, with the pawls a and the stop-pins a), actedupon by the lever Z, to communicate motion to the gears that turn thehands. These pawls or clocks and stops may be of any desired character,and the power from the float m and lever I may be used for any otheroperation which it is adapted to.

I claim as my invention-- 1. A cylinder or Vessel, raised and loweredperiodically by clock-work into and out of Witnesses:
